Question about CyberPower (CP800AVR) UPS System

CyberPower 800 AVR

We had a instant electrical flicker at our home and our CyberPower Surge Protecter went out and started to ring. The ring did not stop until I hit the power button to turn it off. It only rings when turned back on and there is no electricity going through the unit. What should I do??

    This unit sucks! The ENDLESS ringing drove me NUTS! Return it and buy a different brand. I did.

    I have the same problem. It is supposed to be a UPS but what it is doing now is any time there is a surge, the entire unit turns off and rings. It is supposed to maintain power through any surges and even provide battery power in the event of total elctrical failure. Perhaps mine has reached the end of its lifecycle. I know it works, because it has saved me many times. I wish I would have saved the manual so I knew what this ringing indicated.

    I have an HP5000 60" printer pluged into a Cyber Power 800AVR. All of a sudden it started ringing and theres no stopping it unless you turn it off. As soon as you turn it back on it beeps a few times then the ring starts again. Very annoying. Someone please help.

Hi. I've had one since 2003 no problems. Then suddenly I come home and the power had temp gone out, come back on and the tone is constant. I hit the button, on and off. powers, then off, a couple of beeps. Nothing improved it.

I read online...the back up battery eventually wears out and can be replaced! This will happen will all units, it's normal. No biggie and less expensive than a new unit. I haven't replaced mine yet as this all coincided with a new computer purchase and I was planning on getting at least one more unit anyway, so I've just grabbed a 825 off the shelf. I'll figure out ordering a replacement battery as I have time, and perhaps order a couple of smaller units for some other applications in the house.

One of these units is cheaper than the deductible on insurance, and I've had lighting just going overhead take out 2 tv's and such in different houses, 3 different events totalling thousands. My cyberpower protected the tower and computer I'm using now, but others in the house, router, etc were destroyed. You can't risk getting those hits on your insurance if you can help it. If only I'd had one hooked up to the garage door opener, lol. $61 would have saved me $500.

These issues sound like an overload situation. The 60" printer is probably either a laser or thermal and when it warms up the components it will send the UPS in to a "self preservation" mode. Laser printers are notorious for this. It could also be the battery. These haven't been manufactured for quite sometime, so check the battery voltage as it should be above 12 volts after a 24 hour charge in the unit. If it needs a new one, here is the replacement:

Which are the surge protected outlets on a cyperpower 1000AVR?

The surge protected outlets should be identified on the top of the unit. If not identified, all outlets may have surge protection.

Cyber power 685 avr won't reset

Hi Marvin,

If the unit took a hit to it you should check to see if the battery is still good. It may not function properly because of a dead battery.

Electricity was off for several days. When it came back on, VCR/DVD wouldn't stay on. It flashes power/red, then VCR/green, then DiscIn/Green, then Play/Green, then turns off.

There was probably a power surge either when the power went off or when it came back on. There is most likely a problem with the power supply inside of the DVD/VCR. You should either get a new one or take it to a repair shop to be fixed (it needs new parts and it is not user fixable). To prevent this from happening again you should get a surge protecter. Sometimes you might have something that looks like a surge protecter but isn't. Make sure it says surge protecter on it.

My computer won't boot and the CyberPower 825 AVR makes a continuous sound.

It sounds as though the UPS is not receiving power. Check that it's cable is properly plugged into the wall. Also verify that it's internal ground fault interrupter has not tripped, it's usually a little red button on the back of the unit, it should be pressed in and should stay that way, if it pops out then there is a problem with the ground of your electrical outlet. Also check that the breaker for that electrical has not tripped at your fuse box.

Since the UPS is not receiving power the batteries have discharged and that is why your computer cannot start, there is not enough juice from the UPS to boot it. That is also why it is making a noise as most UPS's sound an alarm to indicate that they are not connected to power.

There is a chance that the batteries in your UPS have gone bad or that something has become faulty in your UPS. Try plugging your computer and monitor directly to the wall bypassing the UPS to see if they work fine.

CyberPower 325SL won't work...

NEVER mix surge protectors and UPS!!!. Doing so overloads whoever of the two gets connected to the wall. This equipment is built to be plugged DIRECTLY to the wall. Your unit just crossed it's inner battery. Take it to a recycling center, then stop on your favorite electronis shop and buy a new one.
